I could not sign in. I prompted Yahoo to send the CODE to my Gmail account. Never happened. I tried and tried and tried and tried . . . . . . Yahoo never sent me the code they said they were going to send me. Finally, after a whole lot of doings, I was able to sign in and read my email. I have no cell phone, no mobile phone, and no other phone that Yahoo needs to know of. So, stop asking. I give you my Gmail info and that's enough. Why do you make things so difficult. If i could transfer my contacts to gmail without using the cloud I'd do it in a minute and drop Yahoo email completely. Gmail never pulls the stunt you guys pull. You are just screwing with us.
